2 Answer

  • Answer:

    The length of blue segment is:

    9

    Step-by-step explanation:

    We know that the:

    Length of transverse axis i.e. '2a' is equal to 6.

    i.e. 2a=6.

    Also the distance of a point from one focus is 15.

    and let the length of the blue segment be 'b'.

    " As we know that the absolute value of the difference of distance of a point from the two focus is equal to the length of a transverse axis "

    Hence,

    [tex]|15-x|=6[/tex]

    Hence, we have:

    [tex]15-x=6\\\\15-6=x\\\\\\x=9[/tex]

    Hence, the length of the blue segment is:

    9
